Purpose
Enter global configuration mode on Switch A.
Configure a VTP administrative domain.
The domain name can be from 1 to 32 characters.
Configure Switch A as the VTP server.
Return to privileged EXEC mode.
Verify the VTP configuration on both Switch A and Switch B.
In the display, check the VTP Operating Mode and the VTP Domain
Name fields.
Verify that the VLANs exist in the database on Switch A.
Enter global configuration mode.
Enter interface configuration mode, and define the interface to be
configured as a trunk.
Configure the port to support ISL or 802.1Q encapsulation or to
negotiate with the neighboring interface. You must configure each
end of the link with the same encapsulation type.
Configure the port as a trunk port.
Return to privileged EXEC mode.
Verify the VLAN configuration.
Repeat Steps 7 through 11 on Switch A for a second interface in the
switch.
Repeat Steps 7 through 11 on Switch B to configure the trunk ports
that connect to the trunk ports configured on Switch A.
When the trunk links come up, VTP passes the VTP and VLAN
information to Switch B. Verify that Switch B has learned the VLAN
configuration.
Enter global configuration mode on Switch A.
Enter interface configuration mode, and define the interface to set the
STP port priority.
Assign the port priority of 10 for VLANs 8 through 10.
Return to global configuration mode.
Enter interface configuration mode, and define the interface to set the
STP port priority.
Assign the port priority of 10 for VLANs 3 through 6.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
